JOI-IN V. PILGHER AND JOHN F. BABBITT, OF LOUISVILLE, 'KENTUCKY SAID BAIBBITT ASSIGNOR TO SAID PILCIIER.

SEPARABLE BUTTON.

Application filed August 13, 1923. Serial No. 657,092.

To all whom it may concern.'

Be it known that we, JOHN V. PILCHER and JOHN F. BABBITT, citizens of the United States, and residents of Louisville, in the 5 coun-tyof Jeiferson and State of Kentucky,

have invented certain new and useful Improvements in Separable Buttons, o-f which the following is aspecirrcation.

Our present invention relates to improvements in separable buttons and is shown and described herein as embodied in a sep arable link cuff button, though not limited to this specific use.

rlhe invention aims to provide a button which can be economically manufactured, which will be strong and durable in use, and one in which the parts will be firmly and securely locked together While yet capable of being easily separated or unconpled.

With these and other objects in view, the invention includes the novel features of construction and arrangement and combination of parts hereinafter described, and particularly defined by the appended claims.

An embodiment of our invention is illustrated in the accompanying drawings, in which Figure 1 is a central vertical section through o-ur improved button with the parts separated, the 'section being taken on line 1 1 of Fig. 2.

Fig. 2 is a section taken through the head on line 22 of Fig. 1.

Fig. 3 is a section on line 3--3 of Fig. 2, and

Fig. 4 is a section on line 4--4 of Fig. 2, looking in the direction of the arrow.

Figs. 5, 6 and 7 are views of a modified form.

Referring by reference characters to this drawing, the numeral 1 designates the stud member which may carry any desired form of flange (single or multiple) being shown as embodied in a multiple flange type, the upper flange 1LL being shown and the lower portion of the stud being broken away. The separable head or socket member, com* prises a back piece or collet Q having a tu `bular portion of hub 2a and flange 2h, the hub -being of the proper shape and size to receive the stud 1. The outer edge of the collet is flanged or turned upwardly and the face member or cover 2 of the button has its edge spun or flanged down over the edge of the collet in the customary manner. .i

Within the space thus formed is located a plate member 3 which has a flanged outer edge 3a clamped between the back and cover member, and is provided with a central aperture in alignment with the bore of 4the hub. This plate serves as a support for the stud-engaging means, which consists of an f approximately semicircular spring 4 (preferably slightly exceeding a semi-circle) fittingthe seat formed by the flange 3a and retained in position thereby, the spring haw ing parallel end portions ta which are dea.

The plate member '3 has, at the edge of I its central opening,'upwardly turned flanges 3b, which are provided with recesses at s their ends in which the parallel portions of the spring rest when the stud is not in po sition in the socket, these recesses serving to prevent the spring portions 4a from being deflected upwardly when the stud member is inserted, it being understood that the end of the stud member is rounded, or otherwise shaped to provide a substantially wedge-shaped end, 0r its equivalent, as indicated at 1C, yso that forcible entry of the stud member in the socket will force the spring arms 4a apart until, on complete entry of the studmember, *theyV snap into :the recess `1. Y i v Preferably kthe ends of the spring are formed of substantially S-shape, as shown.

y vWith the spring ends or arms la engaging the recess 1b, it will be seen that the parts are securely locked together. To release the shank from the said arms", we provide wedg- "ing means which takes the form of a push piece 5 stamped from sheet metal and fitting a centrally arranged opening in the cover member 2c. This push piece has depending wedge-shaped portions, or wings 5, lying between the spring ends la on opposite sides of the stud, and just within the flanges 3b, so that an inward push on the push piece 5 will cause the wedges to spread the spring ends 4a and release the stud member.

The margins of the push piece between the wedges are bent outwardly, as indicated curved joint which leaves an intervening space in wliich thespring'X is located, the parallel portions of the spring indicated at mf restiiig on shoulders y and bearing against lugs or ears y. The push piece x 1 is,ofc0urse, correspondingly elongated,

' f vHaving thus described our invention, what we cla-im isi;- f 1.- A button of the separable type, having a-'frecessed stud, a circular socket member to receive the stud,'a spring catch comprising a semi-circular lspring portion terminating iii'gapp-reximately parallel portions to engage said stud, and a push piece having a vwedge-shapedportion actingy parallel to the airis of the stud'and lying between said parallel portions. j

-A button of the separable type having a recessed stud, a socket'member to receive the stud, a spring catch comprising a spring compressible in a direction laterally of the socket member, a plate within thev socket having a flange portion, said spring engag- .ing said flange portion.

A button of the separable type having a recessed stud, a socket member to receive the stud, a spring Catch adapted -to engage the stud, a'p'late within the socket member,

said "spring engaging the plate, said plate preventing vertical movement in both directions of the spring.

` 4:. A bu-tton'of the separable type, having a recessed stud,afsoe-ket member to receive the stud, comprising ashell cover and back securedV together? at their edges, a plate member having a` margin confined between the edge portions of the shell and back, and

having a central opening and upwardly turned flanges adjacent the same with re- Cessed ends, a spring overlying said plate member and having parallel stud engaging arms resting in said notched ends when no stud is held thereby, and a push piece having wedge-shaped portions lying between said spring arms and spaced apart to admit the stud.

5. A Ib-utton of the separable type having a recessed stud, a'socket member to receive the stud, a spring adapted to engage the stud and retain the same within the socket, and a push piece operating through an aperture in the top of the socket and adapted to free the stud from the spring catch, movement of the push piece toward the stud causing compression of the spring.

6. A button of the separable type having a recessed stud, a socket member, to receive the stud, a plate within the socket member,

`a spring catch in proximity to said plate and adapted to engage the stud, said plate having a central aperture through which the stud is adapted to pass, upwardly turned langes adjacent the aperture with recessed ends, the ends of said spring catch engaging the recessed ends of the upwardly turned flanges on the plate,

7. A button of the separable type having a recessed stud, a socket member to receive the stud, a spring catch adapted to engage the stud and retain the same within thc socket, and a plate.` within the socket supporting said spring catch.

8. A button of the separable type having a recessed stud, a socket member to receive the stud, a spring catch adapted toengage the stud and retain the same within the socket, and a plate within thel socket supporting said spring catch, said plate having an upset portion also engaging the spring, which prevents upward movement of the spring.

In testimony whereof, we aliix our signatures.
